Has definitely adapted to new Firefox! Rated 5 out of 5 stars
This Extension, versions 5.0.*, is the perfect tool for fine-tuning the App Menu in Firefox 4.0.*, allowing for substitution of custom menu folders for the standard menu-item expandables as appropriate. The Restart and Configuration menu items in this Extension are quite useful for developers, and additional items can be added to custom sub-menus from both default items and Menu Toolbar functions.
As an example, I have two set-ups in conjunction with the Chris Extension Extension Options Menu (which took up where the James R. Skinner Extension Options Menu left off), on one system running Microsoft Windows 7.0.8001 (which has Extension Options between the default Options expandable and the Help expandable in Column 2), and on another running Ubuntu 10.04.2-LTS (which has Extension Options, along with a custom Tools submenu, between the default Preferences expandable and the default Help expandable).

This Extension is an excellent means of accessing a user subset of the Menu Bar functions when necessary; the included Bookmarks and History buttons complete the package. Combined with Toolbar Buttons, it gives me access to Master Defeat toggles for JScript, Sun Java, images, animations, Adobe Flash, Movies, IFrames, and Cookies from the Menu button.
I have been using this Extension with Strata40 0.6.1 and StrataBuddy 0.6.1 and have been able to test contingency proposals for UI amendments for the still-in-development Firefox 4.0. With Tabs on top, I placed the three included buttons at the left end of the Navigation Toolbar, with the Universal Print and Update Notifier buttons and throbber at the right (I normally pull the Search bar from the Navigation Toolbar, not having used it much at all in several years).
